Figure 9. Viability and density analysis of 3D-bioprinted constructs. (A) Images of constructs captured immediately after 3D bioprinting. (B) Calcein AM/PI
staining of 3D-printed scaffolds cultured in vitro for 24 h (green fluorescence represents live cells; red fluorescence represents dead cells). (C) Statistics of average
optical density (AOD) values of live cells (indicated by green fluorescence). Abbreviations: CA, calcein acetoxymethyl (calcein AM); PI, propidium iodide.
